Definitions

  • the present invention relates to a method and an apparatus in the manufacture of mineral fibres according to the preamble of the claims below and a fiberising rotor arrangement.
  • the structure of the collected primary web is greatly influenced by the conditions in the collecting chamber during the travel of the mineral fibres from the fiberising apparatus to the collecting member. If the flow conditions in the collecting chamber are turbulent and back-eddies exist, the collected primary web becomes slightly nodular and inhomogeneous. The fiberising and collecting processes become difficult to control when the produced amount of fibre increases.
  • - fibre blow-off means which is arranged at the active periphery of the fiberising rotor, and which is arranged to blow off mineral fibres towards a collecting member
  • the fibre blow-off means can comprise a number of blow-off slots, the width of which usually is 10 - 20 mm, preferably 13 - 17 mm, and the height of which usually is 10 - 20 mm, preferably 10 - 15 mm.
  • the number of blow-off slots in a fibre blow-off means can be chosen as needed, for example depending on the length of the blow-off means along the periphery of the rotor.
  • the manner in which the blow-off slot is formed can be chosen according to need.
  • the cross section of the slot can, for example, be round, rectangular or oblong.
  • the forming of the blow-off slots discharge openings is according to one embodiment round and the slots are formed by drilled holes.

Abstract

L'invention concerne un procédé de fabrication de fibres minérales dans lequel un minéral fondu est amené à un premier rotor de fibrage en rotation dans un système de fibrage comprenant au moins deux rotors de fibrage et s'étendant de la surface du fuseau du rotor en rotation à la surface du fuseau du second rotor en rotation et de cet emplacement, successivement à toutes les surfaces de fuseau de tous les rotors suivants possibles. Le minéral fondu prend ensuite la forme de fibres minérales au niveau des périphéries actives des rotors en rotation et les fibres minérales ainsi formées sont dégagées des rotors de fibrage de l'appareil de fibrage à l'aide d'un moyen de dégagement des fibres disposés au niveau des périphéries actives en direction d'un élément collecteur. Un liant est appliqué aux fibres minérales pendant leur formation au moyen d'un élément d'application de liant disposé au niveau des périphéries actives des rotors. La périphérie active d'au moins un des rotors de fibrage est divisée en au moins une première section et une seconde section et un élément d'application du liant et/ou un moyen de dégagement des fibres au niveau de la première section sont commandés indépendamment de l'élément d'application du liant et/ou du moyen de dégagement des fibres au niveau de la seconde section. L'invention concerne également un appareil de fabrication de fibres minérales ainsi qu'un système muni d'un rotor de fibrage.
